Yuraygir horse-cull challenge fails as court leaves removal method to managers

Carmen Jackson’s effort to stop aerial horse culling in Yuraygir National Park began with an urgent court application heard at 1 a.m. in August. It secured a temporary pause and became a dispute over the legal meaning of one word: “removal”. On October 30, 2026, Justice Rachel Pepper dismissed the challenge, leaving the choice of removal method with park managers. ^{3 6 1}

The New South Wales Land and Environment Court judge found that Jackson had not supplied enough evidence to prove aerial culling breached the National Parks and Wildlife Act. The park’s plan of management required feral horses to be removed; how that happened was, Pepper said, “an operational matter”. ¹

That is a consequential defeat for Jackson, but it is not confirmation that shooting has resumed. The dismissal establishes the failure of this legal challenge, not a completed operation, a tally of horses killed or a new timetable for aerial culling.

Jackson argued that the National Parks and Wildlife Service lacked the “statutory authority”—the legal power—to carry out aerial culling in Yuraygir. Her case centred on the management plan’s use of “removal” to describe what should happen to the brumbies. During the September hearing, the government argued that “remove” was “very broad” and did not exclude “killing things”. ¹

The issue was therefore narrower than the wider argument about whether horses should be shot from the air. Jackson needed to establish that the official who authorised their removal and killing had acted unlawfully. Pepper placed that burden on Jackson under the civil standard of proof: the balance of probabilities, meaning more likely than not. ¹

Jackson did not meet that burden. According to ABC News’s account of the reasons, Pepper found that the plan required the “removal of feral horses” and that the secretary held “a broad discretion ... to remove or eradicate feral horses”. The secretary was “authorised, if not required, to remove horses” from the park. ¹

Taken together, those findings reject the restriction Jackson sought to read into the plan. A requirement to remove horses was not treated as a prohibition on killing them. The obligation remained in place, while the means of carrying it out remained an operational decision.

The account of the dismissal and the quoted reasons comes from ABC News. The complete final judgment has not been independently examined for this article. The result should not be stretched into a blanket ruling on every horse-control operation, every animal-welfare concern or every national park in New South Wales.

The proposed Yuraygir operation focused on the Minnie Water area of the Clarence Valley. Earlier reporting identified August 26–28 as the planned shooting dates. Those dates describe what was proposed, not evidence that shooting took place. ^{8 4}

The two-week pause belongs to the earlier stage of the litigation; it is not a new suspension announced with the dismissal. Likewise, September’s account of a decision still pending has been superseded by the October 30 ruling. Neither earlier status should be mistaken for the position after judgment.

A separate change to the park’s paperwork matters here. After Jackson filed her initial injunction application, Yuraygir’s pest-management plan was amended to strengthen its pest-control language and expressly include aerial culling as a method. ABC’s dismissal report places that update before an October 1 hearing. The precise amendment date is not established. ¹

The pest-management plan and the park’s plan of management are not interchangeable. Pepper’s reasoning about the obligation to remove horses concerned the plan of management. The reported addition of aerial culling concerned the pest-management plan. Confusing the two would obscure both the judge’s reasoning and the operational change made during the case. ¹

ABC also reported that the service can update pest-management plans without ministerial approval. The amendment therefore did not require a minister’s sign-off. The amended document itself has not been independently examined for this article. ¹

The immediate legal result is clear: Jackson has lost this route to preventing aerial killing in Yuraygir. What happens on the ground is less clear. The evidence available for this ruling establishes no verified herd estimate, removal target, completed cull total or operation-specific animal-welfare safeguards. Numbers or procedures from another park would not fill those gaps.

Pepper appeared in court for only a matter of minutes, said the judgment would be published and stood the court down. ABC reported that the National Parks and Wildlife Service had been contacted for comment, but carried no response. No post-ruling response from Jackson, appeal filing or timetable for renewed shooting has been established. ¹

The distinction now is between legal authority and operational action. The court has rejected Jackson’s challenge to the former. When the service will act, and on what announced terms, remains unresolved.
